Abstract: Abstract of the Disclosure A method and an apparatus provide an optical switching system (10) which provides independent of viewing angle two system optical transmission states of substantially contaminant-free light. The system includes first and second light gates (12 and 12') of which each has associated therewith contaminant light intensity patterns (48 and 66) with points of local maxima (54, 56, 58, 60, 68, and 70) and local minima (62 and 72) in two system optical transmission states.  The contaminant light intensity patterns are oriented so that the points of local maxima and minima of the contaminant light intensity patterns of one of the light gates generally align with the respective points of local minima and maxima of the contaminant light intensity patterns of the other light gate.  The alignment of contaminant light intensity patterns blocks the transmission of contaminant light in two system optical transmission states, and thereby provides improved viewing angle performance.

Abstract: LASER DIFFERENTIAL QUANTUM EFFICIENCY CONTROL CIRCUIT    Abstract of the Disclosure In an injection laser drive arrangement, variations in differential quantum efficiency are compensated by means of a feedback loop which includes a low pass filter and the usual PIN diode on the rear face of the laser diode.  A second low pass filter, having characteristics identical to the first, filters the input signal.  The outputs of the two low pass filters are compared and integrated to provide a control signal for varying the amplitude of the signal applied to the laser diode.  With this arrangement, laser output variations due to patterns of bits in the input signal are cancelled out in the control signal, which consequently compensates the differential quantum efficiency.     - i -
